Dosage of BTEX (residual solvents)

The determination of BTEX compounds (benzene, toluene, ethylbenzene and xylenes) makes it possible to quantify these volatile aromatic solvents in various matrices such as soils, water, packaging, materials, or industrial products.

These compounds are monitored because of their toxicity and polluting potential, particularly in the environmental, agri-food (migration), cosmetics and polymer sectors.

Analysis is generally performed by gas chromatography (GC), often coupled with mass spectrometry (GC-MS) or flame ionization detection (GC-FID). Samples can be prepared by liquid-liquid extraction, purge and trap, or headspace, depending on the matrix. This method allows for sensitive detection that meets regulatory requirements.

At YesWeLab , we collaborate with a rigorously selected network of laboratories, most of which are certified and/or accredited (ISO 17025, COFRAC, etc.). These laboratories are chosen based on your specific needs, the matrices to be analyzed, and the analytical techniques or methods required.
If you have any specific requirements, please do not hesitate to specify them when submitting your request: our scientific team makes every effort to respond accurately and responsively.
Since 2020, many manufacturers, distributors, and design offices have trusted us to manage their analyses, entrusting us with their samples via our digital platform.
